# title: update schema version
#
# description:
# Update schema_version in meta table to 59

#We need to insert this for new species!
#Unique key will not capture duplicate NULL species_id patches
#So we need to handle this

#Is there a HC for multiple schema_version entries


#SET @schema_version_count=(SELECT COUNT(*) FROM meta WHERE meta_key='schema_version'); 
#This flow control only allows return values to be constants, not selects!
#Would need stored procedure/program/function with IF statement 
#IF (@schema_version_count > 1, select "Found more than 1 meta entry for schem_version. Please resolve", select NULL);
#IF (@schema_version_count = 1, select "updating", select NULL);	
#Or can we just delete and re-insert, living with the meta_id increment 

UPDATE meta SET meta_value='59' WHERE meta_key='schema_version';

# patch identifier
INSERT INTO meta (species_id, meta_key, meta_value) VALUES (NULL, 'patch', 'patch_58_59_a.sql|schema_version');
